Welcome to Flyertalk, JesseBecka Sprague As one who has flown on the Concorde I can attest to the fact that I did see the curvature of the earth.
Having said that, I believe that this discussion is more appropriate for the OMNI Forum. However, as you do not have the requisite posts and length of time on FT you do not qualify for OMNI.
Therefore, I am locking this thread.
